The graph has eight nodes and seven arcs. The first node is
the resource /courses/6.001. An arc labeled students connects this
node to an unnamed node. An arc labeled rdf:type connects
the unnamed node to a node labeled rdf:Bag. Five additional arcs
labeled rdf:_1, rdf:_2, rdf:_3, rdf:_4, and rdf:_5
connect the unnamed node to nodes labeled, respectively, /Students/Amy,
/Students/Tim, /Students/John, /Students/Mary, and /Students/Sue.
All the nodes are represented as ovals.
